Analysis of ASTM A484 321 stainless steel hot rolled bar surface oxidation

1. Production process reasons: This is also one of the factors that cause oxidation of steel products. In terms of production process and product characteristics, ASTM A484 321 stainless steel hot rolled bar manufacturers produce a thin oxidation film on the surface of the product. It is a basic process that reduces the risk of oxidation and is also one of the main features that distinguish stainless steel products from other steel products. However, when the oxidation film is not complete or sustained due to insufficient production processes or carelessness, the oxygen in the air will directly react with some elements in the product, causing surface oxidation of the equipment. .

2. Reasons for the preparation of effective ingredients of the product: In order to reduce product costs, some ASTM A484 321 stainless steel hot rolled bar suppliers reduce the proportion of some key elements such as chromium and nickel, while increasing other elements such as carbon. The composition of ASTM A484 321 stainless steel hot rolled bar, this kind of manufacturing situation that does not strictly implement product specifications and product characteristics to prepare effective ingredients will not only greatly affect the quality of ASTM A484 321 stainless steel hot rolled bar. For example, when the content of chromium in steel pipes is insufficient, not only will It directly affects the corrosion resistance and formability of the equipment, and there are potential quality problems when used in chemical plants, machinery, and manufacturing fields; at the same time, it also affects the appearance and antioxidant capacity of the equipment.

3. Human factors: This is also one of the reasons why some consumers often encounter product oxidation when using steel rods. Some consumers use unreasonable products during use and maintenance. In view of the oxidation of steel products caused by human factors, we must have appropriate product application knowledge and effectively maintain and maintain it on time, thereby reducing the oxidation caused by human error.
